This element defines the placement and properties of the camera in the 3D scene. The camera position and properties modify the view of the scene.
[Example: Consider the following example of a camera in DrawingML:
<a:camera prst="orthographicFront">
<a:rot lat="19902513" lon="17826689" rev="1362739"/>
</a:camera>
In this example, we see a preset camera being defined along with a rotation containing latitude, longitude, and revolution overrides provided that further rotate the camera around the scene. The effect of this camera can be seen on the following shape:

Attributes |
Description |
|
fov (Field of View) |
Provides an override for the default field of view for the camera. Different perspectives can be obtained by modifying this attribute.
[Example: Consider the following example of a fov in DrawingML:
<a:camera prst="perspectiveContrastingRightFacing"
In this example, we see a fov being defined which modifies the default fov for the preset camera. end example]
The possible values for this attribute are defined by the ST_FOVAngle simple type (§5.1.12.24). |
|
prst (Preset Camera Type) |
Defines the preset camera that is being used by the camera element. The preset camera defines a starting point for common preset rotations in space.
[Example: Consider the following example of a prst in DrawingML:
<a:camera prst="perspectiveContrastingRightFacing"
In this example, we see a prst being defined as perspectiveContrastingRightFacing. end example]
The possible values for this attribute are defined by the ST_PresetCameraType simple type (§5.1.12.47). |
|
zoom (Zoom) |
Defines the zoom factor of a given camera element. The zoom modifies the scene as a whole and zooms in or out accordingly.
[Example: Consider the following example of a zoom in DrawingML:
<a:camera prst="perspectiveContrastingRightFacing"
In this example, we see a zoom being used which will zoom the scene by 200%. end example]
The possible values for this attribute are defined by the ST_PositivePercentage simple type (§5.1.12.46). |
